Hypertrophic cardiomyopathy (HCM) is one of the most prevalent hereditary cardiovascular diseases. Eicosanoids are known to play a significant role in cardiovascular diseases and serve as biomarkers. In this study, plasma eicosanoids were profiled by LC-MS in a cohort of 78 healthy individuals and 73 patients diagnosed with HCM. Our findings reveal HCM patients exhibit downregulation of various eicosanoids, including AA, 5,6-DHET, 12-HETE, LXA4, EPA, etc. Notably, the combined predictive model incorporating 12-HETE and EPA demonstrates significant diagnostic value for HCM. Additionally, ten closely related metabolites showed significant positive correlations within the metabolic network graph. Eicosanoids such as 17,18-EEQ, LXA4, and 13-oxo-ODE exhibit significant negative correlations with plasma concentrations of hs-CRP and NT-proBNP in patients. Alterations in eicosanoid metabolism may be implicated in the pathophysiological processes underlying HCM.
肥厚型心肌病（HCM）是最常见的遗传性心血管疾病之一。类二十烷酸在心血管疾病中发挥重要作用，并作为生物标志物。在本研究中，通过液相色谱-质谱联用（LC-MS）对78名健康个体和73名诊断为HCM的患者的血浆类二十烷酸进行了分析。我们的研究结果显示，HCM患者表现出多种类二十烷酸的下调，包括花生四烯酸（AA）、5,6-二羟基二十碳四烯酸（5,6-DHET）、12-羟基二十碳四烯酸（12-HETE）、白三烯A4（LXA4）、二十碳五烯酸（EPA）等。值得注意的是，包含12-HETE和EPA的联合预测模型对HCM具有显著的诊断价值。此外，在代谢网络图中，十种密切相关的代谢物显示出显著的正相关。17,18-二羟基二十碳三烯酸（17,18-EEQ）、LXA4和13-氧代-十八碳二烯酸（13-oxo-ODE）等类二十烷酸与患者血浆中高敏C反应蛋白（hs-CRP）和N末端脑钠肽前体（NT-proBNP）的浓度呈显著负相关。类二十烷酸代谢的改变可能与HCM的病理生理过程有关。
